如何正确地爆炸字符串

Question

How to explode a string, for instance

#heavy / machine gun #test

in order to only get "heavy" and "test" ?

I tried with explode but so far I only got "heavy / machine gun" and "test"

Thanks in advance, Jeremie.

Alternative to explode:

$str = "#heavy / machine gun #test";
preg_match_all('/#([^\s]+)/', $str, $matches);
var_dump($matches[1]);

This will basically find all hashtags in a given string.
